760whp skyline with direct port water injection (corrected)

Wow, that is one nice set up!

Richard , what are the hoses connecting to under the "GT ART" logo and whats the see through plastic box next to the pumps :?:

MY guess: Under the GT ART logo would be water flow sensors, and the see thru box would be seperate fuse panel/box for the WI system.

Richard this is a really neat system/setup, congrats to the owner. Thats a FIA2 behind the pumps correct. Is there a schematic for this setup it would be interesting to see how its designed and how the wiring is done with the two pumps. Two pumps were used because the system is in the trunk? It looks like both pumps feed into a tee that feeds a 30cc accumulator and then outputs to a 6mm line, this line runs to the front and then splits into the two flow sensors, then one outputs to a four way and the other to a Y fitting, then to the jets? What triggers injection? Sorry for the questions, but this looks pretty neat and I'm just curious about how it works.

An HSV will replace the two on/off solenoid in the front of the car this week. The two solenoids are triggered by the ECU - programmed to injection from 6000 RPM on and above a certain boost and throttle angle.

The owner has all the details but I forgot the exact procedure. IT managed to gain some 70- horses and got him running 10.6s quarter all day on street tyres on a very hot day (we call 32C a very hot day in England).

By the way, thanks very much for the womderful pictures (nice looking car by the way), I will resize them and post them to the car-specific thread.

The purple parts are just twin solenoid valves (on/off).

Hi Richard,

very nice installation! How much water are you injecting in each port?
Which mixture are you using?

Best regards,

Hello Bodo,

I will pass on your nice comment to the man responsible for the installation.

At present the company doesn't want this information to be known to the public. The mixture will be "green" - some special mix that they are going to sell on as a a pre-mix.

We have the similar situation when Snow performance refused to tell one of our user what mix is in their Nitrobased mix so that I can test the Aquamist pump's seal here. Typical commercial interest gone a bit overboard.
